Baby Ravi is undergoing phototherapy treatment for Hyperbilirubinemia. Which parts of his body should be covered to prevent tissue damage?

Appeared in: KGMU 2023

Explanation

The correct answer requires identifying the specific body parts that must be shielded during phototherapy despite the need for maximal skin exposure.
The eyes must be covered with opaque patches to prevent retinal damage from the high-intensity light.
The genitalia are covered with a small diaper to protect the sensitive gonads from radiation.
All other areas, including the abdomen and extremities, should remain exposed to maximize the effectiveness of the light treatment in breaking down bilirubin.

Option A: The abdomen must be left exposed to the light. Covering it would significantly reduce the surface area available for treatment, making the phototherapy less effective.
Option C: The extremities (arms and legs) have a large surface area and must be exposed to the light to maximize the breakdown of bilirubin.
Option D: This option is incomplete and incorrect. While the genital area is covered, the abdomen must be exposed. Critically, it omits the mandatory protection for the eyes, which are at high risk of damage.

Clinical Relevance

Nursing practice connection: Knowing Nursing care and safety protocols for neonatal phototherapy helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
A nurse's primary responsibility during phototherapy is to ensure both treatment effectiveness and patient safety.
Incorrectly applied or omitted protection can lead to serious, irreversible harm, such as retinal damage, or render the treatment ineffective.
Nurses must also monitor for side effects like dehydration, temperature instability, and skin rashes, and ensure the infant is repositioned regularly.

How to Approach the Question

First, identify the core clinical procedure in the question: phototherapy for neonatal jaundice.
Recall the primary goal of this procedure, which is to expose as much skin as possible to the therapeutic light.
Next, consider the safety principles and contraindications. Think about which body parts are most sensitive and might be harmed by the treatment.
Evaluate each option by weighing the need for skin exposure against the need for protection. The eyes (retinas) and genitalia (gonads) are known to be sensitive areas requiring protection in this context.
Eliminate options that suggest covering large surface areas needed for treatment (abdomen, extremities) or that omit protection for a critical area (eyes).
